Generally, when we create a suitelet page, we add the script(a suitelet script which is going to be called from another suitelet) to the button of another suitelet page, by which clicking that button from the first suitelet, we can redirect to another suitelet page.

But that will be possible, if either we don’t need any parameter or we know the parameters which are going to be sent to the next suitelet from the beginning(while creating the first suitelet).

Here is an example:

Let’s say, we want a suitelet page, which will be called from an Item record.

That Suitelet page will contain That Item and some other information and a button called “Redirect”.

We want another suitelet script which will be called by clicking that “Redirect” button and we want that Item should be sent as a parameter to the second suitelet to show information regarding that Item.

Here when we will create the first suitelet, we will get the Item from Item record and will populate that in the suitelet page. So here we know the parameter(item) from the beginning. So we can attach the second suitelet to the “Redirect” button of first suitelet.
